IMPROVEMENT IN HORSE-POWERS.

Specification forming part ot' Letters Patent No. 44 ,479, dated September 27, 1864.

To all whom, it may concern.-

Be it known that we, SETE WHEELER and EDGAR JEROME, of Albany,in the county of Albany and State of New York, have invented a new and useful improvement in the construction of horse-powers, by means of which broken or detached links and damaged tread-rails may be easily removed without disturbing the siding or removing'the i'ramework ofthe machine. It is simple and convenient, and possesses advantages which will be herein clearly shown.

The nature of our invention consists in construct-in g a horse-power with a movable panel or doorinserted in, one or both sides ofthe sam e between the uprights or framing, and placed near the back or lower end of the machine. Each movable panel or door is kept in its place by two cast-iron plates or stays, pro' vided with a hooked projection on each lower end, to receive a bolt secured to the upright frame for the purpose ot' supporting the same. rlhe upper end ot' each plate or stay is provided with an offset or slot to receive a button or cam, which slides into the same and keeps the panel or door in proper position, and to remove the saine it' is only necessary to slide back the buttons or cams and push The links and tread-rails can then be raised up and got at with great facility, the broken ones removed, and new ones replaced in less time than it would take to move the framing or siding or take out and replace the guard-rails, which are the only available methods adopted at present, and involve necessity of removing1 bolts, which in the hands of inexperienced workmen are hardly ever replaced in their proper position. The lower part of each panel or door is formed of a part of the guard-rail, and when in its position tits perfectly, and the joint cannot be perceived.

We have fully tested our improvement by applying it to horsepowers recently built, and nd it is convenient and works to good advantage.

Having thus set forth the nature of ourim provement, and to enable others skilled in the art to make and use the same, we will now proceed to describe it, and certify that the accompanying drawings are a full and correct representation ofthe same, like letters corrcsponding with like parts.

Figure l represents a side elevation of a horse-power, showing one of the movable panels or doors in proper position; Fig. 2, a side elevation, with a panel or door removed. Fig?) is an enlarged perspective view of a part of the horsepower, with a movable panel or door removed, to show the manner ot' disconnecting the links and tread-rails 5 Fig. 4, a separate view of a movable panel or door. Fig. 5 is an end view of the same.

A A A A are the uprights or framing of the horse-power, secured to the track-rail or beam B and mortised into the lower beam, C; D the siding applied to the upright frame A A A A; E, the links; E, the tread-rails; G, one of the movable panels or doors; H H', the plates or stays secured to the same, provided with hooked projections I I' on the lower ends and offsets or slots K K' in the upper end of each, to receive the buttons or cams L L' 5 M, one ofthe guard-rails, part 0f which forms the bottom of each movable panel or door. N N' are bolts, applied to the uprights or frames A A', to receive the hooked projections I l' and sustain the panel or door Gr, which can be removed by sliding back the buttons or cams L L', and pushing in from the outside. P P', Fig. 3, are bars, used to litt the tread-rails.

We claim Constructing horse-powers with one or more movable panels or doors, substantially as described, and for the purpose specitied.
